IMPROVEMENT IN PORTABLE RAILROAD-TRACKS.

Specification forming part of Letters Patent No. 221,817, dated November18, 1879; application filed August 23, 1879.

To all whom it may concern:

Be it known that I, ALFRED HEYN, of the city, county, and State of NewYork, have invented certain new and useful Improvements in PortableRailroad-Tracks, of which the following is a specification.

In the accompanying drawings, Figure 1 represents a top view of myimproved portable railroad-track, shown with interlocking sections. Fig.2 is a top view of the same, with sections detached; and Fig. 3 is adetail vertical longitudinal section on linezr as, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to improvements in portable railroad-tracks, bywhich not only a more reliable interlocking of the sections, but also,at the same time, an alternating railjoint, is obtained.

The invention consists of a portable railroadtrack made in sections, therails of each section being extended at diagonally-opposite ends, whilethe other'rail ends extend only to the middle of the tie. Each sectionhas a lockingpiece, adjoining the shorter rail end, which interlockswith the elongated rail end of the adjoining section. The end tie ofeach section has also a second binding-piece, that bears on theinterlocking-piece of the adjoining section to prevent the dislocationof the section.

Referring to the drawings, A A represent the sections of my improvedportable railroadtrack. Each section A is constructed of crossties at a,which are, preferably, of iron of suitable cross-section, and of rails12 I), riveted to the erossties. The end ties a a are wider than theintermediate ties for giving a better support for the meeting ends ofthe rails.

The rails of each section A are extended at diagonally-opposite endsbeyond the end tie to a certain distance, while the other rails stopshort at the middle of the end ties. The

sections when connected form thus a continuous line of track, in whichthe rails alternately break joint, so as to facilitate .the running ofthe rolling-stock on the track.

Each section A is provided, adjoining the shorter railends, with lookingpieces B, which are riveted firmly to the end tie. These looking-piecesB are slightly rounded off at the side adjoining the rail, to allow thetrack-sections to be laid at an angle toward each other when roundingcurves. They are also slightly bent upward at the ends, as shown in Fig.8, to facilitate the ready pushing together and connecting of thesections. The lockin g-pieces of the tracksections form, with theelongated rails of the sections, a rigid and reliable connection of thesections when the weight passes over the same, first at one side andthen at the other, owing to the alternating jointsof the rails. Theinterlocking of the sections equalizes the weight and renders the trackmore secure and firm.

Each end tie has, furthermore, a binding piece, 0, at such distance fromthe elongated rail that the locking-piece B may freely pass in. It isthen retained by the angular side of the binding-piece G, and therebythe sidewise dislocation of the sections prevented. sections are thusconnected, so as to resist the vertical pressure of the weight as wellas longitudinal and lateral strains, and form thereby a smooth andreliable interlocking track.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- As an improvement in portable railroad The
